摘要為了弄清楚阻燃處理木材的燃燒及其熱傳導規律，該研究採用多功能耐火實驗爐模擬典型火災的發生過程，測定了未處理、阻燃劑水溶液浸漬處理、塗刷防火塗料白皮松和水曲柳木材的燃燒及木材內不同位置的升溫過程。Especially in the north slope, the broad - leaved wood of red pine, the animal ( insect ), plant ( tall tree, shrub, herb ) and the tree grows plentiful. the living creature is numerous, and the complete vegetative chain of formation is with the food net, provided the proper and living space for the animal ( insect ) and plant ( tall tree, shrub, herb )
長白山作為我國北方溫帶地區最高的山峰，保存了最為典型和完整的森林生態系統，特別是在長白山北坡的紅松闊葉林帶，樹種豐富，生物繁多，形成完整的食物鏈和食物網，對生活于其中的動物（昆蟲） 、植物（喬木、灌木、草本）提供了適宜的生活空間。Niche breadth of four dominate populations at three age groups was studied by the methods of resource utilization ability and ratio. the result shows that : symplocos sectchuanensis is a typical gengeration species whi ch resource utilization ability is strong, and distribution is wide. meanwhile, go rdonia acuminata, castanopsis fargesis and pinus massoniana specialized at some d egree in resource utilizationm, their distribution is limited. especially, the ju venile of pinus massoniana specialized outstandingly. with the devlopment of pinu s massoniana, which is the pioneer population in mt. jinyun, the environment become s unfit to it ' s juvenile. it turns to needle and evergreen broad - leaves mixed fo r est. because the tolerance toward shading of gordonia acuminata is lower than tha t of castanopsis fargesis, gordonia acuminata will be substituted by castanopsis fargesis and other evergreen broad - leaves species are the edificators. the popul ation ' s ability of resource utilization is the inner factor of population distri bution and community succession. the distribution of light and the concentrate of nutrient ( such as n ) is the outer factors of community succession
對縉雲山森林植被的4個優勢種群3個年齡級生態位寬度進行了研究.結果表明，川灰木利用資源的能力最強、分佈廣，為典型的泛化種.大頭茶、栲樹、馬尾松對資源的利用在一定程度上特化，分佈上有一定的局限性.馬尾松的中齡組與幼齡組特化現象十分顯著.縉雲山森林植被的先鋒種馬尾松的發展，導致環境的改變不適于其幼齡個體的生長，群落演替到針闊葉混交林階段，最後發展為以栲樹等為建群種的常綠闊葉林.種群的資源利用能力，是種群分佈與群落演替的內在原因，光因子和營養元素（如n ）是群落演替的主要外部動力It divides the main vegetation of the headwater region of huangpu river into 4 categories based on field survey and observation and methods of factor analysis and systematic cluster analysis and according to the degree of soil and water conservation function : deciduous trees and shrubs are category 1 which shows very strong soil and water conservation function ; tea plantation, grasslands and pine trees are category 2 which has stronger function ; the category 3 is moso bamboos and broadleaved evergreen trees which have stronger permeability and erodibility, but the permeable performance is not outstanding, the capacity of soil moisture storage common and soil and water conservation function moderate and ; the category 4 is uncovered land where the soil and water conservation function is very weak and its permeability, erodibility, erosive resistance and soil moisture storage capacity are all notably smaller than that of the other lands
摘要在野外調查、實測的基礎上，採用因子分析、系統聚類分析的方法，根據土壤層水土保持功能的強弱，將黃浦江源區主要植被類型分為4類：落闊林、灌木林為第一類，表現出很強的水土保持功能；茶園、草地、松林為第二類，土壤水土保持功能較強；毛竹林、常綠闊葉林表現出較強的抗蝕性和抗沖性，但滲透性能並不突出，土壤貯水能力也一般，水土保持功能中等，為第三類；裸露地水土保持性能很差，單獨作為第四類，其滲透性、抗蝕性、抗沖性、土壤水庫容都顯著小於其他各樣地。Study on spatial pattern of ovum, pupa and emergence holes of pisodes yunnanensis
